Simple Steps To Install LC Circuit

This app is used to calculate LC resonant circuit. It is suitable for hobbyist or electronic engineers.


Features:
1. Calculate resonant frequency by capacitor and inductor values
2. To find out combinations of capacitance and inductance making a desired resonant frequency
3. Save all combinations in a CSV (Excel) file
4. Use preferred values of capacitors and inductors


Features in PRO version only:
1. selectable preferred value
2. No Ads
3. No limitation


Note :
1. For those who need support please email to the designated email.
Do NOT use either the feedback area to write questions, it is not appropriate and that is not guaranteed that can read them.

SIMPLE AND FAST to use is the key to productivity. This is a tiny app that bears fruit quickly when you begin to use it faster and faster to find the answers to your tuned circuit design or modification questions. DON'T grumble about it's lack of bells and whistIes until AFTER you have learned to be productive with it. GOOD APP!
